Chemical Weathering

Explanation:

Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals. These minerals are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.

Answer:

If More solute is added and it does not dissolve,then the original solution was saturated. if the added solute dissolves,then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturated.

well u see the offspring of asexual production will be identical to the parent because it only needs 1 parent where as sexual production requires 2 parents so it would look like both parents

Explanation:

Protons, Neutrons and Electrons are the three primary subatomic particles that form an atom.

Protons and Neutrons are large particles and are densely compacted into the nucleus of the atom. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge.

Together the protons and Neutrons make up the mass of the atom.

Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons. They are found in electron clouds that surround the nucleus and their movement and properties provide for the bonding characteristics of each atom.

Answer:

chemical composition

The temperature of the xenon : 180.863 K

Combined with Boyle's law and Gay Lussac's law  

[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]

P1 = initial gas pressure (N/m² or Pa)  

V1 = initial gas volume (m³)  

P2 = final gas pressure  

V2 = finalgas  volume  

T1 = initial gas temperature (K)  

T2 = final gas temperature  

P1=251 kPa

T1=-18+273=255 K

V1=1.9 L

P2=205 kPa

V2=1.65 L

[tex]\tt \dfrac{251\times 1.9}{255}=\dfrac{205\times 1.65}{T_2}\\\\T_2=\dfrac{205\times 1.65\times 255}{251\times 1.9}=180.863~K[/tex]

Answer:

I need more information.

Explanation:

Answer:

The answer is metalloids.

The metalloids are a unique group of elements that share properties of both metals and nonmetals. They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.

Answer:velocity is positive

acceleration negative?

Explanation:

Answer:

110 °C

Explanation:

The following data were obtained from the question:

Initial pressure (P1) = 0.538 atm

Initial temperature (T1) = 256 °C

Initial volume (V1) = 437 mL.

Final pressure (P2) = constant = 0.538 atm

Final volume (V2) = 316 mL

Final temperature (T2) =?

Next we shall convert 256 °C to Kelvin temperature. This Can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T1) = 256 °C

Initial temperature (T1) = 256 °C + 273 = 529 K

Next, we shall determine the new temperature of the gas as illustrated below:

Pressure = constant

Initial temperature (T1) = 529 K

Initial volume (V1) = 437 mL.

Final volume (V2) = 316 mL

Final temperature (T2) =?

Applying the Charles' law equation, we have:

V1 /T1 = V2 /T2

437/529 = 316/T2

Cross multiply

437 × T2 = 529 × 316

437 × T2 = 167164

Divide both side by 437

T2 = 167164 / 437

T2 = 382.5 ≈ 383 K

Finally, we shall convert 383 K to celsius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T(K) = 383 K

T(°C) = 383 – 273

T(°C) = 110 °C

Therefore, the new temperature of the gas is 110 °C

Answer:

Option - It would happen faster at warmer air temperatures

Explanation:

The chemical process of converting organic matter such as plants, litter into organic soil, or organic compost called decomposition and perform by decomposers such as fungus or bacteria.

Like all other living organisms, decomposers also live in an optimal range of temperature. The major decomposers normally lie in the range of 30 to 40-degree celsius. Any type of fluctuation in this range might slow down the reaction of decomposition.

Answer:

B

Explanation:

I believe because intrusive stays within the earth

The accurate statement regarding the intrusive igneous rock is that It forms inside the earth.Hence, Option (B) is correct.

Intrusive, or plutonic, igneous rock forms when magma remains inside the Earth's crust where it cools and solidifies in chambers within pre-existing rock.

The magma cools very slowly over many thousands or millions of years until is solidifies.

Therefore, The accurate statement regarding the intrusive igneous rock is that It forms inside the earth.Hence, Option (B) is correct.
